2. Exemplary Item

In one embodiment, an item/shipment 103 may be any tangible and/or physical object. In one embodiment, an item/shipment 103 may be or be enclosed in one or more packages, envelopes, parcels, bags, goods, products, containers, loads, crates, items/shipments banded together, vehicle parts, pallets, drums, the like, and/or similar words used herein interchangeably. In one embodiment, each item/shipment 103 may include and/or be associated with item/shipment information/data. Some exemplary item/shipment information/data is shown in FIG. 16. As will be recognized, the item/shipment information/data may include an item/shipment identifier. Such item/shipment identifiers may be represented as text, barcodes, tags, character strings, Aztec Codes, MaxiCodes, Data Matrices, Quick Response (QR) Codes, electronic representations, and/or the like. A unique item/shipment identifier (e.g., 123456789) may be used by the carrier to identify and track the item/shipment 103 as it moves through the carrier's transportation network. Further, such item/shipment identifiers can be affixed to items/shipments 103 by, for example, using a sticker (e.g., label) with the unique item/shipment identifier printed thereon (in human and/or machine readable form) or an RFID tag with the unique item/shipment identifier stored therein. Such items/shipments may be referred to as “connected” items/shipments 103 and/or “non-connected” items/shipments 103.

In one embodiment, connected items/shipments 103 include the ability to determine their locations and/or communicate with various computing entities. This may include the item/shipment 103 being able to communicate via a chip or other devices, such as an integrated circuit chip, RFID technology, Near Field Communication (NFC) technology, Bluetooth technology, Wi-Fi technology, and any other suitable communication techniques, standards, or protocols with one another and/or communicate with various computing entities for a variety of purposes. Connected items/shipments 103 may include one or more components that are functionally similar to those of the carrier computing system 105 and/or the third party computing entity 110 and/or the carrier personnel entity 115, as described elsewhere herein. For example, in one embodiment, each connected item/shipment 103 may include one or more processing elements, one or more display device/input devices (e.g., including user interfaces), volatile and non-volatile storage or memory, and/or one or more communications interfaces. In this regard, in some example embodiments, an item/shipment 103 may communicate send “to” address information/data, received “from” address information/data, unique identifier codes, location information/data, status information/data, and/or various other information/data (all are generically referred to herein as item/shipment information/data.

In one embodiment, non-connected items/shipments 103 do not typically include the ability to determine their locations and/or might not be able communicate with various computing entities or are not designated to do so by the carrier. The location of non-connected items/shipments 103 can be determined with the aid of other appropriate computing entities. For example, non-connected items/shipments 103 can be scanned (e.g., affixed barcodes, RFID tags, and/or the like) or have the containers or vehicles in which they are located scanned or located. As will be recognized, an actual scan or location determination of an item/shipment 103 is not necessarily required to determine the location of an item/shipment 103. That is, a scanning operation might not actually be performed on a label affixed directly to an item/shipment 103 or location determination might not be made specifically for or by an item/shipment 103. For example, a label on a larger container housing many items/shipments 103 can be scanned, and by association, the location of the items/shipments 103 housed within the container are considered to be located in the container at the scanned location. These can be referred to as “logical” scans/determinations or “virtual” scans/determinations. Thus, the location of the items/shipments 103 is based on the assumption they are within the container, despite the fact that one or more of such items/shipments 103 might not actually be there.

FIGS. 14-16 are exemplary input received by and output produced in accordance with various embodiments of the present invention.

1. High Level Operation/Data Flow

Reference will now be made to FIG. 5, in which there is illustrated an exemplary process for the security screening process 500 according to various embodiments of the present invention. As illustrated therein, there is provided according to various embodiments a streamlined and automated solution for screening packages slated for transport by one or more vehicles (e.g., screening of air cargo prior to transport thereof on aircraft, and the like). Exemplary and non-limiting advantages achieved include more consistent screening results, increased screening capacity, and reduced screening staffing requirements. The improved consistency is achievable in certain embodiments via integration with the security screening system described herein with one or more of an X-ray scanning system and a material handling system, both of which as will be detailed further below. The increased screening capacity and the reduced screening staffing requirements are achievable in certain embodiment at least in part due to the automation provided via the multi-tiered screening processes detailed herein, wherein in at least one embodiment the net volume of items screened per day may be doubled. In another embodiment, the net volume of items screened per hour may be tripled. Of course, a wide range of improved results may be obtainable, as should be understood from the description following herein.

As may be understood generally from FIG. 5, the screening process initiates upon receipt of localized data 501, which may include data indicative that one or more packages are entering the screening layout (see layout 700 of FIG. 12, illustrating unload locations, conveyor mechanism (see also FIG. 13, as described further below), X-ray imaging systems (see also FIG. 13), and sorting systems (see also FIG. 11)), data comprising one or more parameters associated with whether or not a package should be subjected to additional levels of screening, and/or data comprising one or more algorithms configured to automatically execute the multi-tiered and progressive levels of screening by the security screening system described herein. Thereafter, according to certain embodiments, Level 1 screening 502 is performed, which comprises an automated (i.e., unstaffed) process that obtains certain data from the packages as they pass through the screening layer.

If one or more of the parameters remain unsatisfied (i.e., if a threshold is not met, or if certain data (e.g., a package tracking number) is blurry as obtained, or the like), the security screening process proceeds to Level 2 screening 503. Therein, a brief manual assessment may be conducted according to various embodiments, whereby discrepancies or ambiguities in the obtained or viewed (e.g., via an XPG as described further below) data may be resolved. If unresolvable or otherwise triggering one or more parameters requiring additional screening, Level 3 screening 504 may commence. Therein, in an untimed environment additional screening may be conducted, which may in certain embodiments include the capture of new images/data from the packages. In certain instances where even this degree of scrutiny remains inconclusive, Level 4 screening 505 may be performed, whereby alternative screening methods (e.g., a materials handling screening process, as described further below) and additional data capture methods may be performed, again manually and in an untimed environment. Should Level 4 screening further fail, Level 5 screening 506, which consists of containment of the package until further notice/resolution commences.

It should be understood that according to various embodiments, at any point during the process illustrated in FIG. 5, should additional screening not be necessary, the package/item under scrutiny may—at that point—be released for additional sortation/transportation. This may be understood with reference as well to the high level data flow illustrated in FIG. 6, whereby as various levels of security screening are satisfied, disposition and sorting may occur, for example via integrated scanning and sorting systems, each of which as may incorporate additional levels of automation, as described elsewhere herein.

It should also be understood that according to various embodiments, at any point during the process illustrated in FIG. 5, one or more notifications or alerts may be generated by the security screening system and via the security screening process 500 described herein. Exemplary and non-limiting examples of notifications and/or alerts of this nature are provided in FIGS. 15A-B, whereby in FIG. 15A a manual threat assessor (whether primary or secondary, as described in further detail below) may receive an email notification 1000 that a particular item has been flagged for Level 2 screening 503, as of a certain time. FIG. 15B illustrates a comparable text notification 1100 that the same threat assessor may receive at a mobile device or the like (see FIG. 1) under the control of the threat assessor. As will be detailed elsewhere herein in conjunction with description of each of the discrete levels of screening (i.e., Levels 1-5), these types of notifications may be sent to one or more users of the system, either in a manual (e.g., in response to a user request for update) manner or in an automatic fashion (e.g., upon occurrence of a particular event within the analysis performed automatically via he security screening process 500 described herein.

In certain embodiments, flow rates may be additionally optimized by fully integrating the screening system described herein with a material handling system, such as of the type described in U.S. Pat. No. 8,386,277; the contents of which as are incorporated by reference herein in their entirety. A materials handling system is advantageous, for example, because in certain jurisdictions (e.g., the United States), distributors of controlled substances (i.e., a drug or chemical whose possession, use, or transport are regulated under the United States' Controlled Substance Act or otherwise, including prescription medications, narcotic drugs, and the like) are required to be registered by the Drug Enforcement Administration (DEA). Still further, under such regulations, a distributor must design and operate a system to disclose “suspicious orders” of controlled substances. Suspicious orders may include orders of unusual size, orders deviating substantially from a normal pattern, and orders of unusual frequency. Failure to do so may result in fines and/or loss of privilege to ship such substances.

In view of the above requirements, drug distributors (including carriers responsible for transporting controlled substances for such distributors typically institute a simple, threshold-based calculation to determine suspicious orders. For example, a customer may be assigned a monthly threshold for each family of controlled substances and if the customer attempts to place an order that exceeds its monthly threshold, the order is flagged as suspicious. However, this threshold approach simply sets a number (e.g., threshold) based on various factors and does not automatically adjust over time as more orders are received from customers. Further, this threshold approach does not consider other customers who may be placing orders for controlled substances within the same family. As a result, a customer's threshold may not be as accurate with regard to a “typical” customer who places orders for controlled substances in the same family. In addition, a customer threshold may become outdated (e.g., “stale”) over time and not representative of what should be used to flag suspicious orders. As a consequence, the distributor's system may miss orders that should be flagged as suspicious and this may leave the distributor open to possible fines and/or loss of privilege to distribute such substances. Therefore, utilization of a comprehensive, integrated, and “smart” material handling system, such as of the type described in U.S. Pat. No. 8,386,277, the contents of which as are incorporated by reference herein in their entirety, proves advantageous in that it automatically accounts not only for the shipment being evaluated, but also historical order information for both the customer placing the order and for other similarly situated customers. Coupling this type of system only further enhances the integrated carrier review and government review (see also FIG. 11) achievable via the multi-tiered security screening process 500 (see FIG. 5 again) described herein.

An exemplary process utilized by a materials handling system such as of the type described in U.S. Pat. No. 8,386,277 may be understood with reference to FIG. 14, which illustrates an exemplary user interface depicting a series of checks that may be applied to a specific order received from customer ZZ12345678 for 400 units of Clonazepam (e.g., drug code 2737). The interface displays the results of each check performed for the order 901, 902, 903, 904. For instance, the interface displays that the order has failed checks one, two, and three. In addition, the interface provides selection mechanisms 905, 906 (e.g., buttons) that allow a user to view the control charts associated with the first check and the second check. Further, the interface provides a description of each check 907, 908, 909, 910 and the results of each check along with instructions based on the results 911, 912, 913, 914. Further details about the scope and nature of the checks and the results thereof, beyond what information is depicted in FIG. 14 may be understood with reference further to U.S. Pat. No. 8,386,277; the contents of which as again have been incorporated by reference herein in their entirety.

In certain embodiments, flow rates and/or consistency of screening results may also be additionally optimized by fully integrating the screening system described herein with a package X-ray screening system that utilizes an X-Ray penetration grid (XPG), such as of the type described in U.S. Patent Application Pub. No. 2015/0063539; the contents of which as are incorporated by reference herein in their entirety. An exemplary configuration of this nature may be understood with reference momentarily to FIG. 13, which illustrates an X-ray screening device (or system) 840 that includes an XPG 850 that comprises a radiopaque grid oriented such that the radiopaque grid elements are neither parallel nor perpendicular to the “direction of travel” of the conveying mechanism 841. In use, the item 810 to be scanned is oriented relative to the XPG such that, when the item and XPG are located between an X-ray emitter 842 and a detector 843, X-ray waves 845 produced by the X-ray emitter that pass through the item to be scanned must also pass through the XPG before reaching the detector. Because the radiopaque grid elements are evenly spaced apart and neither parallel nor perpendicular to the direction of travel of the conveying mechanism, no ghosted grid elements are visible in the generated image, such that radiopaque objects contained in a scanned item are easily and/or accurately identified in the generated image; further, a ghosting phenomenon encountered via conventional X-ray scanning systems is avoided.

To better understand this phenomenon, it should be understood that generally when associating a mesh or grid structure with items to be scanned, the ghosting phenomenon described above may inadvertently cause at least a portion of the mesh or grid structure to appear visible in the created image, although the electromagnetic waves did not penetrate completely through the item. For example, ghosted streaks may appear to extend at least a portion of the grid elements in the created image and the resulting image may therefore show these ghosted streaks superimposed over items even where the electromagnetic waves did not penetrate completely through the item. Thus, the mesh or grid structure may be “ghosted” (i.e., appear) in a resulting scan image, even where the item being scanned has not, in reality, been fully (or sufficiently) penetrated to actually detect all portions of the conventional mesh or grid. Consequently, personnel viewing the created image may be led to believe that a complete scan through the entirety of an item was achieved. This “ghosting” phenomena is referred to herein as “ghosting,” “ghosting lines,” “ghost lines,” “ghost images,” “ghosted images,” “ghost radiation,” “ghost signals,” and/or “ghosted lines,” all of which as should be understood to generally and interchangeably describe this phenomena.

Historically, efforts to reduce the impact of ghosting have focused on creating improved detector elements, or incorporating complex algorithms utilized to minimize the impact of ghosting. However, such solutions are prone to errors due at least in part to electromagnetic noise and other imperfections in the received signal. For example, even where grids are used, if such are oriented in a manner that results in the grid lines thereof being parallel to the direction of travel, ghosted lines may appear, although such may contain certain distortions therein. While users could conceivably identify such distortions, the risk of a user overlooking a particular distortion remains prevalent. Thus, utilization of an X-ray scanning system that includes an XPG as described herein and as also described in further detail in U.S. Patent Application Pub. No. 2015/0063539, the contents of which as are incorporated by reference herein in their entirety substantially minimizes the impact of “ghosting” so as to ensure sufficient penetration of all scanned items without resorting to secondary item handling and the like.

It should be understood from the above passages that according to those embodiments in which an X-ray scanning system and/or XPG are utilized, various characteristics of the items/packages being scanned may be determined in an automatic fashion. For example, various pieces of information may be read from a package label 1200, such as the type illustrated herein in FIG. 16. The information obtained may be in human-readable form, machine-readable form, and/or a combination of both. Still further, in certain embodiments, the information obtainable via utilization of the X-ray scanning system and/or XPG may include dimensional/volume/weight information associated with the item/package, which information may be utilized to automatically determine and/or validate shipping costs associated therewith.

2. Level 1 Screening Procedure(s)

Reference will now be made to FIG. 6, in which there is illustrated an exemplary process flow for Level 1 Screening 502 procedures according to various embodiments of the present invention. According to various embodiments, this level of screening commences with the compilation or identification of at least certain localized data 502A, which may comprise at least some indication that one or more packages are entering a screening area, for example, via a conveyor mechanism as illustrated in FIGS. 12 and 13 and as described previously herein. Upon receipt of at least such an indication—which may in certain embodiments be received automatically from an operations or scanning system (see FIG. 11)—the Level 1 screening 502 commences in step 502B. Therein, an automated series of steps commences, including the capture of package tracking identifiers (e.g., a 1Z/PTN number or the like), the capture of an x-ray image of the package or item under review, and at least some portion of data required for generation of a screening decontrol message.

It should be understood that according to various embodiments, the screening decontrol message is configured to facilitate decontrol (i.e., release) of the package upon clearance of the package through (or at any stage of) the multi-tiered security screening process described herein. In certain embodiments, the screening decontrol message includes at least some combination of the following data elements: a record number, a system source type code, a record creation time and date stamp (GMT), a record type, a country code, a facility number, a package tracking identifier (1Z/PTN or the like), an event time and data stamp (GMT), a scanning user identifier (where manual scanning involved), a sort data, a sort code, a clear scan type (e.g., indicating the basis and level of release), a method of screening, a screening user number (where manual), a screening user last name, a screening user first name, a primary screening required indicator, a secondary screening required indicator, a record end indicator (e.g., a code that is machine-readable, wherein in certain embodiments the screening decontrol message is automatically generated and/or distributed to users of the system and/or to certain components or systems within or external to the screen system described herein). Of course additional and/or alternative data elements may be contained within the screening decontrol message, as may be desirable and/or particular advantageous in certain embodiments.

Returning now to FIG. 6, during step 502B and the performance of Level 1 screening according to various embodiments, a determination will be automatically made in step 502C as to whether Level 2 screen in is necessary. This determination in step 502C may be based upon various parameters and/or factors, including in certain embodiments in which an auto-sort engine may consider captured X-ray images of the item or package under review and in view thereof makes a comparison to a textual merchandise description associated with the item or package, and/or evaluates a commercial invoice further associated with the item or package so as to determine any discrepancies between any of the obtained and/or evaluated data. Where any discrepancies and/or ambiguities (e.g., differing data, blurriness in images obtained, or the like) exist, Level 1 screening 502 may proceed to step 502E, wherein Level 2 screening is initiated. Otherwise, where no discrepancies and/or ambiguities are identified, Level 1 screening proceeds to step 502D, wherein the package or item may be released for further transport/handling.

According to various embodiments, during step 502E one or more notifications may be generated as Level 2 screening is determined to be a necessity. Exemplary notifications and/or alert messages—as may be sent to one or more users of the system—are illustrated in at least FIGS. 15A-B. In conjunction with—or in certain embodiments concurrently with but separate from—one or more data items may be saved to the screening system or otherwise transmitted to one or more threat assessors (primary or secondary; remote or otherwise, all as will be detailed elsewhere herein) so that pertinent data is available and/or otherwise readily accessible for Level 2 screening, as described below. In certain embodiments, the notifications, alert messages, and/or data may be automatically transmitted during step 502E; in other embodiments, at least some portion of the data may only be transmitted upon request therefor by the Level 2 screening staff/personnel, however as may be deemed beneficial and/or desirable for various applications.

In these and still other embodiments, during step 502D, should it be automatically determined via the screening system that Level 2 screening is not necessary, release of the package or item for sorting, further transport and/or handling, or the like may involve generation of a decontrol message (as described previously herein). This message may likewise be manually or automatically transmitted to one or more users of the system for receipt thereby as in FIGS. 15A-B (or otherwise), for example via one or more devices (see FIG. 1) being used by the individual at that time. Still further, according to various embodiments, the decontrol message may be automatically transmitted to one or more sub-systems or systems—either internal or external to the screening system described herein—so as to facilitate continued automated (in part or in full) handling of the package or item. This may be understood, for example, with reference to FIG. 11, which illustrates at least a sorting system that may be automatically (or otherwise) utilized to further direct the package or item upon receipt of a disposition.

It should be understood with reference to both steps 502D and 502E, that upon disposition following Level 1 screening, one of two paths may be taken by the package or item under evaluation. Via step 502D, as described above, a sorting system or a further package handling system may be utilized to release the package or item from further screening or scrutiny. In an analogous fashion, via step 502E, the system according to various embodiments may be configured to automatically sort and/or reroute a package or item needing Level 2 screening in a direction (e.g., along a conveyor belt) different than that which would occur were Level 2 screening deemed unnecessary. With reference momentarily to FIG. 12, it may be understood according to various embodiments that where Level 2 screening is deemed necessary—for example following passage of the package or item through the X-ray scanner (visible and labeled as such in FIG. 12)—the package—upon being flagged for Level 2 screening may be held immediately downstream of the X-ray scanner for manual review by “L2 screeners”—as identified also in FIG. 12. In other embodiments, the packages/items may be otherwise diverted or handled for Level 2 screening; however, in all these and still other embodiments, it should be understood that no decontrol message—so as to release the package for transit and/or out of the screening process—would be generated pending Level 2 screening, the details of which as will be described further below.

3. Level 2 Screening Procedure(s)

Reference will now be made to FIG. 7, in which there is illustrated an exemplary process flow for Level 2 Screening procedures according to various embodiments of the present invention. According to various embodiments, this level of screening commences upon receipt (by the screening system or by one or more users/assessors associated with the system) of one or more notifications and/or data that Level 2 screening is necessary and/or desirable. Following this occurring in step 503A, the process continues to step 503B, wherein Level 2 screening is performed, such that a determination may be made in step 503C as to whether or not Level 3 screening is required. If not, release of the package in step 503D may occur, in an analogous fashion as described herein with respect to release of a package following Level 1 screening in step 502D. If so, the Level 2 screening process continues to steps 503E and 503F, wherein appropriate flagging of the package or item for additional review or assessment occurs and wherein still further notifications and/or data are transmitted so as to facilitate that additional review or assessment.

Returning with reference to FIG. 7 to steps 503B and 503C, the performance of Level 2 screening so as to determine whether or not Level 3 screening is required involves according to various embodiments a manually performed and timed procedure. As illustrated in FIG. 12, in certain embodiments this procedure may be performed adjacent a conveying machine; in other embodiments, it may be performed remotely. In any of these and still other embodiments, it is envisioned, however, that Level 2 screening involve a manual assessment of the package or item under scrutiny, as compared to the automatic screening that occurred during Level 1. In this sense, Level 2 provides an additional layer of scrutiny, where deemed necessary and/or where otherwise the automated Level 1 screening may have identified discrepancies and/or otherwise been deemed insufficient for a certain package or item. It should be understood, however, that is desirable for, via the screening system described herein, that a majority of packages pass Level 1 screening without the need for additional (e.g., Levels 2-5) screening.

According to various embodiments, as mentioned, Level 2 screening in steps 503B and 503C is performed under a time constraint by an identified Level 2 Screen personnel. In certain embodiments, only one individual will perform Level 2 screening upon any particular package, although in other embodiments, a secondary or redundant screening personnel may be utilized. In at least one embodiment utilizing a single Level 2 screener, the time constraint may be within a range of 12 to 20 seconds. In other embodiments, the time constraint may be less than 12 seconds or greater than 20 seconds, with the understanding that in these and still other embodiments the time constraint for Level 2 screening will be relatively short (e.g., less than a couple minutes, at most).

According to various embodiments, where Level 2 screening is invoked, in addition to the time constraint for review described above, a time constraint may be placed upon the timing for transmission of supporting data to the Level 2 screeners for conducting of the Level 2 screening. In certain embodiments, at least the captured x-ray image of the package, the determined tracking identifier, and some portion of data necessary so as to generate a decontrol message (if appropriate, following Level 2 screening) must be provided to a global repository. In at least one embodiment, these types of data must be provided within one minute of capturing the x-ray image. In other embodiments, the data must be provided within one minute of a determination that Level 2 screening is necessary. In still other embodiments, although greater than one minute, it should be understood that the data provided is accessible to Level 2 screeners in a near real-time fashion.

According to various embodiments, in addition to timing constraints for data provision and data review by Level 2 screeners, initiation of Level 2 screening triggers further timing constraints relative to various types of data handled and/or otherwise transmitted by the screening system described herein. In certain embodiments, the global repository must not only have the image available for viewing within approximately five minutes of the x-ray image capture (or of a determination that Level 2 screening is necessary), but any such flagged images for a particular package or item must be retained for at least thirty days following the capture thereof. In other embodiments, viewing may be within a relative short time period (between 2 and 10 minutes following image capture or Level 2 screening flagging); likewise, image retention may be for greater than (or less than) 30 days, however as may be desirable. As another non-limiting example, images may be retained for 60 days. In any of these and still other embodiments, it should be understood that in addition to the images being retained, it may be further required that all data provided for and generated via Level 2 screening be retained, as outlined herein, for example for a certain period of retention time. This information should be globally accessible, for example via a global repository, as described previously herein.

Returning now with reference to FIG. 7, where Level 2 screening determines that Level 3 screening is necessary, step 503E involves the flagging of data for primary and/or secondary remove assessment. Remote assessment during Level 3 should, as an initial matter, be contrasted with the proximate assessment during Level 2 screening, the latter as may be understood with reference to the Level 2 screeners positioned adjacent to a conveyor mechanism in FIG. 12. For initiating remote assessment during Level 3 screening, upon determination that such is necessary, in certain embodiments, at least some portion of the data associated with a package or item (e.g., an image thereof, the 1Z/PTN number, or the like) may be flagged for primary and/or secondary remote assessment, as will be described elsewhere herein. So flagging the data for primary and/or secondary remote assessment in step 503E (which assessment will occur during Level 3 screening, described further below) will cause generation of one or more notifications and/or the transmission of data necessary for identified primary and/or secondary remote assessors to perform the requisite Level 3 screening. As mentioned previously herein, the data may be transmitted separately from the one or more notifications, such that—as a non-limiting example—the data may be retrieved only upon actual initiation of Level 3 screening by the Level 3 assessor(s).

In certain embodiments, it should also be understood that the notifications generated in step 503F may be not only to the Level 3 assessors, but also to other users associated with the screening system described herein. For example, supervisory personnel may wish to be notified of all packages triggering Level 3 screening requirements. As another non-limiting example, triggering of Level 3 screening requirements may trigger one or more external notifications, such as to a government or third-party assessor, operating as a “fail-safe” of sorts where this degree of scrutiny is deemed necessary over a particular package or item. It should be understood in these and other scenarios described elsewhere herein (e.g., for Level 4 screening), decontrol of the package or item from the screening process described herein (or from under the control of the screening system described herein) may require—where manual assessments are involved—sign-off or some sort of authorization from all personnel actively reviewing the package or item; authorization or sign-off from one assessor where more than one are involved will in these and other embodiments be insufficient to trigger release of the package or item via generation of a decontrol message or otherwise.

4. Level 3 Screening Procedure(s)

Reference will now be made to FIG. 8, in which there is illustrated an exemplary process flow for Level 3 Screening procedures according to various embodiments of the present invention. According to various embodiments, this level of screening commences upon receipt (by the screening system or by one or more users/assessors associated with the system) of one or more notifications and/or data that Level 3 screening is necessary and/or desirable. Following this occurring in step 504A, the process continues to step 504B, wherein Level 3 screening is performed, such that a determination may be made in step 504C as to whether or not Level 4 screening is required. If not, release of the package in step 504D may occur, in an analogous fashion as described herein with respect to release of a package following Level 1 screening in step 502D. If so, the Level 3 screening process continues to steps 504E and 504F, wherein appropriate flagging of the package or item for additional review or assessment occurs and wherein still further notifications and/or data are transmitted so as to facilitate that additional review or assessment.

Returning with reference to steps 504B and 504C of FIG. 8, the performance of Level 3 screening so as to determine whether or not Level 4 screening is required involves according to various embodiments a manually performed and untimed procedure. In certain embodiments, Level 4 screening will remotely share not only the obtained x-ray image and at least a merchandise description (and potentially further data—for example a commercial invoice) via the global repository for access thereby by at least a primary remote assessor, but also initiate alternative screening procedures, such as that described elsewhere herein for materials handling (see also FIG. 14). For purposes of conducting any of these remote assessments, one primary remote assessor and up to five secondary remote assessors may be maintained. In at least one embodiment, flagging the image for primary remote assessment (which may occur during the conclusion of Level 3 screening) will automatically notify the primary remote assessor requesting assistance and providing a link to at least the package image. The primary remote assessor may then, during the course of Level 4 screening during steps 505B and 505C request and/or otherwise obtain further information so as to conduct the requisite assessment.

In certain embodiments, flagging an image or package for primary remote assessment may be supplemented by secondary assessment. If such assistance is needed from a secondary remote assessor, the image will be flagged not only for primary but also for secondary assessment. As a result, in these and other embodiments, at least one secondary assessor will be selected from a list of available (e.g., the up to five secondary assessors) secondary assessors, and a notification will be generated and transmitted to the secondary remote assessor selected. In at least one embodiment, an image may be flagged for one primary and one secondary remote assessor; in still another embodiment, an image may be flagged for one primary and up to five secondary remote assessors. In yet other embodiments, multiple primary and/or multiple (and more than five) secondary remote assessors may be available and/or selected for conducting of Level 4 screening, depending upon the degree of scrutiny desired. Certain assessors at Level 4 may be internal to the carrier; others may be external, including for example the provision of a third party government-based assessor, which may be beneficial where the item being transported in the package is a regulated substance or the like, as will be described elsewhere herein.

According to various embodiments, in addition to or instead of the primary and secondary remote assessment described above, alternative screening procedures may be implements, whether manually or in an automated fashion. In at least one exemplary embodiment, an at least partially automated materials handling screening process, configured to further identify and determine whether a package is suspicious or not based at least in part upon the contents thereof, may be employed, as described previously herein. Any one or more of additional or alternative screening processes may be employed in this fashion during Level 4 screening, either internally by the carrier or externally thereto and external to the screening system described herein. It should be understood, however, that throughout such features are integrated—at least in part—with the security screening system described herein, at least in so far as necessary to complete Level 4 screening, as outlined in FIG. 9. It should also be understood that manual capture in Level 4 may include not only of a new x-ray image, but of also additional screening data and/or a package tracking identifier—all as may be necessary for regeneration (validation) of a decontrol message upon completion of Level 4 screening or otherwise.

As mentioned, according to various embodiments, during Level 4 screening the remote assessors (primary or secondary) may only be able to see the x-ray images flagged for remote assessment, with that visibility being provided via the global imaging system (i.e, the global repository) described elsewhere herein. In certain embodiments, a new x-ray image may be requested and obtained during Level 4 screening. In at least one embodiment that may occur via coordinated electronic communication between the Level 4 assessors and on-site screening or operation personnel at the conveyor mechanism.

Returning now to FIG. 9, should the package be designated for release following Level 4 screening, a decontrol message may be generated and provided within the system. In certain embodiments this may occur in an automated fashion; in other embodiments, at least some degree of manual capture of certain data necessary for generation of a screening decontrol message (as described previously herein) may be involved. As a non-limiting example, in at least one embodiment, the names and identifies of the primary (and/or secondary) Level 4 threat assessors may be manually entered and/or at least validated by the assessors themselves.

According to various embodiments, as mentioned, above, even Level 4 screening may remain insufficient to satisfy one or more parameters or conditions so as to permit generation of a screening decontrol message and/or release of the package from the security screening process described herein. In such instances, Level 4 screening may be requested and/or otherwise initiated via step 505F, which request/initiation may occur in a similar fashion to that involved with passage of the screening process from Level 1 to Level 2 and/or Level 2 to Level 3 and/or Level 3 to Level 4, all as detailed previously herein.

5. Level 4 Screening Procedure(s)

Reference will now be made to FIG. 9, in which there is illustrated an exemplary process flow for Level 4 Screening procedures according to various embodiments of the present invention. According to various embodiments, this level of screening commences upon receipt (by the screening system or by one or more users/assessors associated with the system) of one or more notifications and/or data that Level 4 screening is necessary and/or desirable. Following this occurring in step 505A, the process continues to step 505B, wherein Level 4 screening is performed, such that a determination may be made in step 505C as to whether or not Level 5 screening is required. If not, release of the package in step 505D may occur, in an analogous fashion as described herein with respect to release of a package following Level 1 screening in step 502D. If so, the Level 4 screening process continues to steps 505E and 505F, wherein appropriate flagging of the package or item for additional review or assessment occurs and wherein still further notifications and/or data are transmitted so as to facilitate that additional review or assessment.

Returning with reference to steps 505B and 505C of FIG. 9, the performance of Level 4 screening so as to determine whether or not Level 5 screening is required involves according to various embodiments a manually performed and untimed procedure, much like that performed under Level 3 screening. In certain embodiments, Level 3 screening will remotely share the obtained x-ray image and at least a merchandise description (and potentially further data—for example a commercial invoice) via the global repository for access thereby by at least a primary remote assessor, as may have been identified during the conclusion of Level 2 screening, as described above. In at least one embodiment, one primary remote assessor and up to five secondary remote assessors may be maintained. In at least this embodiment, flagging the image for primary remote assessment (which may occur during the conclusion of Level 2 screening) will automatically notify the primary remote assessor requesting assistance and providing a link to at least the package image. The primary remote assessor may then, during the course of Level 3 screening during steps 504B and 504C request and/or otherwise obtain further information so as to conduct the requisite assessment.

In certain embodiments, flagging an image or package for primary remote assessment may be supplemented by secondary assessment. If such assistance is needed from a secondary remote assessor, the image will be flagged not only for primary but also for secondary assessment. As a result, in these and other embodiments, at least one secondary assessor will be selected from a list of available (e.g., the up to five secondary assessors) secondary assessors, and a notification will be generated and transmitted to the secondary remote assessor selected. In at least one embodiment, an image may be flagged for one primary and one secondary remote assessor; in still another embodiment, an image may be flagged for one primary and up to five secondary remote assessors. In yet other embodiments, multiple primary and/or multiple (and more than five) secondary remote assessors may be available and/or selected for conducting of Level 3 screening, depending upon the degree of scrutiny desired. Certain assessors at Level 3 may be internal to the carrier; others may be external, including for example the provision of a third party government-based assessor, which may be beneficial where the item being transported in the package is a regulated substance or the like, as will be described elsewhere herein.

According to various embodiments, during Level 3 screening the remote assessors (primary or secondary) may only be able to see the x-ray images flagged for remote assessment, with that visibility being provided via the global imaging system (i.e, the global repository) described elsewhere herein. In certain embodiments, a new x-ray image may be requested and obtained during Level 3 screening. In at least one embodiment that may occur via coordinated electronic communication between the Level 3 assessors and on-site screening or operation personnel at the conveyor mechanism.

Returning now to FIG. 8, should the package be designated for release following Level 3 screening, a decontrol message may be generated and provided within the system. In certain embodiments this may occur in an automated fashion; in other embodiments, at least some degree of manual capture of certain data necessary for generation of a screening decontrol message (as described previously herein) may be involved. As a non-limiting example, in at least one embodiment, the names and identifies of the primary (and/or secondary) Level 3 threat assessors may be manually entered and/or at least validated by the assessors themselves.

According to various embodiments, as mentioned, above, even Level 3 screening may remain insufficient to satisfy one or more parameters or conditions so as to permit generation of a screening decontrol message and/or release of the package from the security screening process described herein. In such instances, Level 4 screening may be requested and/or otherwise initiated via step 504F, which request/initiation may occur in a similar fashion to that involved with passage of the screening process from Level 1 to Level 2 and/or Level 2 to Level 3, both as detailed previously herein.

6. Level 5 Screening Procedure(s)

Reference will now be made to FIG. 10, in which there is illustrated an exemplary process flow for Level 5 Screening procedures according to various embodiments of the present invention. According to various embodiments, this level of screening commences upon receipt (by the screening system or by one or more users/assessors associated with the system) of one or more notifications and/or data that Level 5 screening is necessary and/or desirable. Following this occurring in step 506A, the process continues to step 506B, wherein Level 3 screening is performed, such that a determination may be made regarding further handling of the package in step 506C. In at least one embodiment, Level 5 screening entails containment of confirmed suspicious or noncompliant packages. In certain embodiments containment may be indefinite; in other embodiments, one or more additional actions may be taken so as to potentially mitigate the containment of the package. As a non-limiting example, one or more notifications of the containment and/or data associated otherwise with the Level 5 screening result(s) may be transmitted to one or more users associated with the security screening system described herein.

7. General Observations regarding Levels 1-5 Screening Processes

As will be recognized, as a package or item leaves or is released from each level of screening, either an automated screening decontrol message will be generated by the screening system or a manual security decontrol message will be captured from data compiled by one or more manual/remote threat assessors. In certain embodiments, even where control is passed to a subsequent level (e.g., passage from Level 1 to Level 2 for further screening, as compared to clearance out of the system from Level 1 alone), a decontrol message will be generated, such that a decontrol message will be captured and retained for each of the multiple levels of screening undergone by a particular package or item. The system may be configured in certain embodiments to consolidate or otherwise group decontrol messages for multiple levels of a single package screening prior to transmission of the final decontrol message, so as to ensure final sort/handling requests are made on the basis of a final decontrol message, versus one prior incurred.

As will also be recognized, where throughout various automatic and/or manual operations have been described relative to certain of the Levels 1-5 of the screening process herein, in certain embodiments levels beyond Level 1 may be automated, in part or in full, as may be desirable or advantageous for particular applications. In still other embodiments, where time constraints have been outlined herein, it should be understood that specific time durations—whether for review, provision of data, or retention of data—are exemplary and non-limiting in nature. Across all embodiments, it should be understood that review and provision of data should be done in a relative timely, even in a near real-time fashion, whereas data retention should be relatively more long-term focused, depending upon priorities and/or system requirements for particular applications. For example, data retention may need to be much longer than thirty (30) days in some instances where sensitive government-related materials are being transported.

According to various embodiments, where indicated that primary and/or secondary threat assessors may access or otherwise obtain certain data—including x-ray images, merchandise descriptions, commercial invoices, and the like—it should be understood that such data may in certain embodiments not only be electronically accessible, but also printable or otherwise transmittable by the assessors. Data may likewise be accessed and/or printed (and/or otherwise handled) by individuals who are users of the screening system but not assessors, as may be desirable. For instance, a supervisor may wish to access and/or print all Level 4 screening associated data for packages handled under his/her supervision.

According to various embodiments described herein, internal staffing personnel (e.g., Level 2 screeners) are able to view and/or print images, merchandise descriptions, commercial invoices, and other such data, as outlined above, and also able to flag images or any portion of the data accessed and assessed, whereby the flags placed or associated therewith are also conveyed to the receiving party thereof. In this manner, external assessors and/or government assessors may be restricted to accessing only that data which is flagged, which in some instances may be less than all of the data associated with a particular package, as may be desirable in certain instances.
